Just opposite the Chongqing People's Auditorium, the free national-level museum is worth visiting. The entrance is Wuyang Hanxuan. Although it has been repaired, it is also very spectacular. There are complete Han monuments and a small number of white crane beam stone carvings on the first floor. The museum is not very big. It is a good place to understand Bayan culture. Not far from the famous Zengjiayan No. 50 and Guiyuan (the place where Chongqing negotiated), you can visit it together
